PUMP.

To all whom it may concern Be it known that I, JAMES A. NORTON, acitizen of the United States, residing at Odebolt, county of Sac, andState of Iowa, have invented certain new and useful Improvements inPumps; and I do declare the following to be a :full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the characters of reference markedthereon, which form a part of this specification.

My invention relates to improvements in pumps, my object being toprovide a device of this character which, while exceedingly simple inconstruction, shall have a relatively large pumping capacity for a givenamount of power expended. I V

In my improvement I employ two pistons cooperating in the stand-pipe andmoving simultaneously in opposite directions, whereby a double-actionpumping operation is obtained.

The two pump pistons are operated by means of rods co-axially arranged,one rod being hollow and the other passingtherethrough. These two rodsare respectlvely .connected with pitmen, the latter being connectedwit-h a rotatable ring at diametrically opposite points, whereby, as thermg is rotated by means of suitable power, the

. rods are simultaneously moved in opposite directions, giving acorresponding movement to the pistons carried by the said rods. Apulley, which may be connected by means of a belt with any suitablemotor, is connected with one of the pitmen, the pitmans wrist-pinconnecting the rotary ring and power pulley, the said connection beingmade beyond the center or" the pulley to correspond with theYVl'lStnPlHS distance from the center of its ring.

Each of the pistons is provided with a check-valve, which opens duringthe downward movement to allow the water to pass therethrough, andcloses during the upward movement, whereby the water is lifted and apartial vacuum produced tocause the water to follow the upwardly movingpiston.

Having briefly outlined my improved construction, I will proceed todescribe the same in detail, reference bemg made to the ac- PatentedFeb. 17, 1914.

companying drawing, in which is illustrated an embodiment thereof.

In this drawing: Figure 1 is a side elevation partly in sectionillustrating my improved pump. Fig. 2 1s a view of the upper part of thepump viewed at right angles to Fig. 1, being a view looking in the direction of arrow 2, Fig. 1. Fig. 3 is a View similar to Fig. 1 showing theupper part of the pump, with the pitmen, however, in different relativepositions from their positions in Fig. 1. Fig. 4 is a sectional view ona larger scale, showing the two pistons arranged in operative relationwith thestand-' plpe removed. Fig. 5 is a fragmentary sectional view ofthe construction illustrating one piston and the lower extremity of thestand-pipe.

Fig. 6 is a sectional view on a larger scale, illustrating the twopiston rods and showingthe manner of joining the sections of which theymay be composed. V

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the standpipe of the pump, in which arelocated two pistons G and 7. The lower extremity of the stand-pipe isprovided with a cap 8 threaded upon the lower extremity of thestand-pipe and carrying a flat check-valve '9 adapted to open inwardlyas the lowermost piston rises. The lower extremity of the stand-pipe isalso provided with a perforated bulb 10 forscreening'the water as itpasses to the pipe.

The lowermost piston 7 is connected with a rod 12 which passesthroughthe piston 6 and thence upwardly through a hollow rod 13 which isconnected with the piston 6 by means of short rods 14 arranged inparallel relation, their lower extremities being secured to a relativelythin block 15 centrally arranged in the shell of the piston and formedintegral therewith, as illustrated in provided with a centrally arrangedopening 1 through which the rod 12 passes. The lower extremities of theshort rods 14 are connected with a cross bar 16, which, in turn, isconnected by a coupling sleeve 17 with the lower extremity of the hollowrod 13. The two rods extend upwardly above the ground, the upperextremity of the hollow rod being rigidly securedto a cross head thedrawings,'see Fig. 4. This block 15 is v 41 slidably mounted on guiderods 4:2, the

upper extremity of the rod 12 being con ring 30 rigidly supported on theupper extremities of the guide rods 42. A second pitman 34 is providedat its lower extremity with a bearing 25 connected with a wristpin 26with which the cross head 18 is pro- \'ided. The upper extremity of thepit-man 34L is provided with a bearin 27 connected with a wrist-pin 28connecting the rotary ring 24: and the power pulley 29. The wrist-pin 28is located diametrically opposite the wristpin of the ring 24 and it isconnected with the pulley 29 at the same distance from the center of thelatter as from the center of motion of the rotary ring.

The ring 24 has its periphery provided with a circumferential grooveforming a half bearing for balls 31 which engage a smaller groove formedin the stationary ring 30', which constitutes a support for the rotaryring. The stationary rin 30 is composed of two parts, which, asillustrated in the drawing, are connected by cap-screws 32 or othersuitable fastening devices, whereby they are readily detachable andreplaceable whenever occasion may require. It will be understood that inorder to place the bearing balls 31 in place it will be necessary toremove the upper member of the stationary ring 30. After the balls arein place, the ring member may be put in position.

In order to properly balance the structure and distribute the power onopposite sides of the axis of the piston rods, the pitmen 19 and 34 areconnected with the rotary ring 24 on opposite sides of the latter. Thepower pulley 29 also serves as a flywheel in the operation of the pump.As illustrated in Figs. 2 and 3 of the drawing, the power pulley 29 isprovided with a crank 33 provided with a handle 35 to permit manualoperation of the pump if desired. Each of the pistons 6 and 7 is V-shaped at its upper extremity, as shown at 36, and is provided withcheclovalve members 37 arranged to open inwardly toward the axial centerof the pump rods during the downward movement of the piston. Thisopening feature is illustrated in Fi 1 and 5 of the drawing.

-Where the well, or shaft, is of considerable depth, the pump rods 12and 13 will be formed in sections "and suitably connected together. InFigs. 6 I have illustrated one way of connecting these sections. Let theletter A designate two sections of the hollow rod 13. These sections maybe connected together by a sleeve 13, the latter being interiorlythreaded at its extremities to receive the corresponding exteriorlythreaded portions of the sections A. Again, the sections C of the rod1.2 have a threaded connection with a short sleeve 1), the latter beinginteriorly threaded to receive the exteriorly threaded portions of therod sections.

From the foregoing description, the use and operation of my improvedpump will be readily understood. hen the pump is in operation, the twopistons (i and 7 move simultaneously in opposite directions, each of thepistons moving alternately upwardly and downwardly. Referring to Fig. 1,it will be observed that the two pistons 6 and 7 are respectively at thelimit of their upward and downward movement since their pitmen 19 and314. are directly in alinement, hence it must be assumed that thestand-pipe 5 is filled with water between the two pistons, and that thewater also fills the standpipe above the piston 6 of the dischargenozzle 39. It must also be assumed that during the upward movement ofthe piston 6 the water above the piston in the stand-pipe has beencarried upwardly, causing a continuous discharge from the nozzle 39 intothe chute, or trough, 40. Now as the rotary ring 24 continues itsmovement. from a position shown in Fig. 1, the piston 6 will. descendand the piston 7 ascend in the stand pipe. As the piston 6 movesdownwardly, its checkvalve members 37 will open, (see Fig. 5) and allowthe water between the two pistons to pass upwardly therethrough, thiswater being lifted during its passage through the piston 6 by the risingpiston 7. These check-valve members 37 are, of course, closed inresponse to the pressure of the water during the pistons risingmovement. Hence, as the piston 7 is lifting the water in the stand pipeand this water is allowed to pass freely to the piston 6, the water willbe lifted in the stand-pipe and keep up a constant discharge or flow ofwater through the noz zle 39. From this it will be understood that whenthe pump is in operation one of the pistons is practically always on theupward movement, since no appreciable time elapses during the stoppingof the pistons move ment in one direction and the beginning of itsmovement in the opposite direction, and for this reason there will be acontinuous flow of water through the discharge nozzle 39 during theoperation of the pump, giving practically twice the flow that could beobtained if a single piston only were employed. Again, very little poweris required to operate the pump, since during the upward movementof thewrist-pin connected with one pitmah, the diametrically located wristpinon the ring 24 is making its downward movement and the weight of theparts connected therewith is advantageously applied to balance theupwardly moving parts connected with the first named wrist-pin. It willthus be observed that the construction is exceedingly well-balanced,and, therefore, easily and economically operated.

Having thus described my invention, what I claim is:

1. In a pump, the combination of a cylinder, pistons located therein andoperably equipped with check-valves, the pistons being in axialalinement and cooperatively arranged, rods respectively connected withthe pistons and co-a-Xially alined, cross heads with which the rods arerespectively connected, one cross head having an opening through whichthe rod of the other cross head passes, guides for the cross heads, a.ring-bearing rigidly secured to the guides, a

ring rotatably mounted in the said bearing, pitmen connected with therotary ring at diametrically opposite points, the said pitmen beingrespectively connected with the cross heads, substantially as described.

2. In a pump the combination witha pipe of two cooperating pistonslocated therein and equipped with check valves to allow the water toflow therethrough in one direction, a ring bearing rigidly secured atone end of the pipe, a ring rotatably mounted in said bearing andconnected in operative relation with the pistons, whereby when the ringis rotated the said pistons will be moved simultaneously in oppositedirections.

In testimony whereof I affix my signature in presence of two witnesses.
